Prior authorization for rehab: What you need to know
Published April 5, 2025 · 7 min read · Updated April 2026
Reviewed for accuracy by licensed clinical professionals.
Prior authorization is insurance's requirement that treatment be approved before it begins. Understanding the process reduces barriers.
How it works
The treatment facility contacts your insurance. They provide clinical information justifying the level of care. Insurance approves or denies. If approved, treatment begins. If denied, appeal rights exist.
What you can do
Most treatment facilities handle prior authorization for you. Ask specifically whether they will manage this process. If denied, request peer-to-peer review (your doctor talks to their doctor). Internal appeal with additional clinical documentation. External review as a final option.
